Polypropylene fibers are synthetic fibers made from isotactic polypropylene obtained through propylene polymerization, known as polypropylene in China. These fibers offer high strength, excellent toughness, good chemical resistance, microbial resistance, and low cost, making them widely used in industries such as ropes, fishing nets, safety belts, luggage straps, safety nets, sewing threads, cable sheaths, geotextiles, filter fabrics, paper felt, and reinforcement materials for paper.

Polypropylene woven geotextiles, manufactured utilizing the excellent properties of high strength, acid and alkali resistance, antimicrobial, and equal strength in dry and wet conditions, can reinforce civil engineering projects built on soft soil foundations (such as dams, reservoirs, highways, railways, etc.), evenly distributing load bearing across the geotextile, ensuring uniform subgrade settlement and reducing ground cracking. When constructing slopes, woven polypropylene geotextiles can stabilize the slope, minimize slope failure, shorten construction time, and extend the slope's lifespan. For bearing heavy loads, composite geotextiles with woven geotextiles and nonwoven as the base can be used. Polypropylene fibers can be used as filling material for concrete and plaster, enhancing the impact resistance and waterproof thermal insulation properties of concrete.
